GS4A012872BT

GS4A012872BT Description

The GS4A012872BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 28.7KΩ resistance and an ultra-tight ±0.1% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a ±100ppm/°C temperature coefficient, ensuring stable performance in varying environmental conditions. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), it is engineered for reliability in precision circuits. The SOIC-C series construction offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for easy surface-mount assembly.

GS4A012872BT Features

• High Precision: ±0.1% absolute tolerance for critical analog/digital signal conditioning.
• Isolated Elements: Four independent resistors in a single package, reducing board space and improving signal integrity.
• Robust Construction: Ceramic substrate and thin-film technology ensure low noise and long-term stability.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-grade environments (though not PPAP/automotive certified).
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for compatibility with standard SOIC assembly processes.
• Non-RoHS Compliant: Ideal for legacy or specialized applications requiring traditional materials.

GS4A012872BT Applications

This resistor network excels in:

• Precision voltage dividers and bridge circuits in test/measurement equipment.
• Signal conditioning for ADCs/DACs in medical devices or industrial sensors.
• Feedback networks in op-amp circuits requiring matched resistances.
• Legacy system upgrades where ceramic reliability and isolation are prioritized over RoHS compliance.

Conclusion of GS4A012872BT

The GS4A012872BT combines precision, isolation, and compactness, making it a standout choice for engineers needing stable resistor networks in space-constrained designs. Its ceramic construction and thin-film technology offer superior performance over polymer-based alternatives, particularly in high-temperature or high-voltage scenarios. While not automotive-qualified, its 0.1% tolerance and low TCR make it ideal for professional-grade electronics where accuracy is paramount.
